Original post by TabrisThat's not really one of Superman's powers, afaik. He can move at super-speed so that everything may seem slower, almost frozen to him, though.
And if people really want to argue power levels, it depends entirely on the writing of Superman.
For example, there's one issue of All-Star Superman where he is shown to be pushing against 200 quintillion tons with one arm, which is not the upper limit of his powers. The rest of this is me paraphrasing something I've read and doing a bit of my own [bad] math.
The average power level of an average man is supposed to be 5. Say the average man weighs about 80kg and can bench press his own weight. 1 ton = 907.18kg according to Google, so Superman can push 181,436,000,000,000,000,000,000kg, which is the equivalent of 2,267,950,000,000,000,000,000 average men and if each of those men has a power level of 5, Superman's power level (by DBZ standards) would be something like 11,339,750,000,000,000,000,000
That's not even the most powerful Superman. Golden age Superman was able to move an entire solar system, as an example.
According to Google, Gogeta's power level was 2,500,000,000 and though he may not be the most powerful in the DB story, he's not far from the top. So Superman alone, is the equivalent to something like 4,535,900,000,000 Gogetas.
Not to mention Superman's array of ridiculous powers, access to unworldly technology allowing him stuff like the ability to banish people to other dimensions and a genius level intellect and all sorts.
Superman has managed to come back from the dead, as well. Kryptonite may be his most obvious weakness, but it isn't his biggest. Besides that, it depends entirely on the setting. Kryptonite from one universe does not affect Supermen of another. There was a crossover event some years ago where a Golden Age reality breaking Superboy started wreaking havoc in the comics; they tried to use kryptonite on him, but it didn't affect him.
I'm not a massive fan of power levels, especially DBZ ones. But when it comes down to it, Superman is overpowered to hell and back and there'd never be a Goku vs Superman situation anyway; they'd bro up.
Edit: and boy do I sound autistic 14-year-old in this post.
